About the Role
Join a small, senior team at a seed-stage AI infrastructure company building an enterprise context layer that makes AI agents reliable, accurate, and secure for critical business operations. As a Full Stack Engineer, you will own product surfaces end-to-end, from customer-facing interfaces to the APIs and data models underneath. Your work will directly shape how engineers understand and interact with a complex, distributed platform.
What You'll Do
-
Own complete product surfaces end-to-end, covering interfaces, APIs, and data models.
-
Split your time roughly 60% on frontend and API layer work and 40% on backend services.
-
Make complex system behavior legible and fast for engineers using the platform.
-
Define architecture, ship it to production, monitor its behavior, and fix what breaks.
-
Make product and design calls independently, without handed-down specs or design files.
What We're Looking For
-
5 or more years building and shipping full-stack applications in production.
-
Proficiency with a modern frontend framework such as React or Vue, with an eye for making complex behavior intuitive.
-
Strong backend fundamentals, with hands-on experience in Python, Go, Node.js, Java, or equivalent.
-
Experience designing and shipping product surfaces end-to-end without detailed specifications.
-
Comfort making architectural decisions independently and owning them through production.
-
Experience with databases and data modeling for systems requiring real-time performance.
-
A builder-oriented background with a track record of startup-speed execution.
-
Genuine full-stack capability, comfortable going deep on distributed systems while also touching UI.
-
Nice to have: experience with knowledge graphs, semantic systems, or graph databases; distributed systems, real-time inference, or agent-based systems; infrastructure or developer-facing products; enterprise data systems or data integration.
